R.R. 300 (6 B) (XX. 368. 9.9.13) E.P. 4920. ROLLS-ROYCE LIMITED. INSTRUCTIONS. 15023 To: O.O for Works Order No.: C & S Dept / 411/13 Re: REAR SPRINGS 4 hor. 1913 Customer's No.: X910 Please note that Mr Royce wishes us to test the rating of these springs over their whole range of action, to see if they behave like a common helical spring or not. The load necessary to cause each inch of movement from free to the point of maximum deflection should be taken & we can then plot a characteristic curve. The springs to be tested are the present standard springs with sheared ends. Springs of constant thickness of plates. get this done early AW Signed: Money This Sheet must be filed on completion of the work. | ||
